I recently completely rebuilt my 302 H.O. motor and spent about $3,500 doing so. I put in a mild cam, forged internals, upgraded almost everything, but nothing extremely radical, just something that would work for a daily driver with a little more horse power. Any way, I broke in my engine right. I used non-detergent oil until I hit 500 miles then switched over to regular. I waited 1000 miles until I completely opened it up. Everything was fine until I noticed a ticking noise a few days later but it wasn't there before I did so. You can only here the ticking noise at idle, anything past 1,500 RPM and you can't notice it. I have no power loss, and it still runs and drives great, but this noise is driving me crazy. Any Suggestions?
